COIN-CONTROL FOR MOTOR-VEHICLES.

useful Improvement in; Goin-Control for Motor-Vehicles, of which thefollowing is a specification. I 1

Our invention relates to improvements in devices of the type illustratedin United States Letters Patent No. 964,845, dated July 19, 1910, andits object is to improve the same in certain particulars hereinaftermore fully set forth.

In the drawings, Figure 1 represents a front elevation of a completedevice embodying our invention and Fig. 2 a similar view of the devicewith the front cover and certain of the working parts removed. Fig. 3 isa detail View of the device for winding Fig. 4 is a view in transversevertical section of the device of Fig. 1. Figs. 5 and 6 are detail viewsof portions of the mechanism which will be hereinafter more fullyreferred to. Fig. 7 is a diagram of the electric circuits and apparatus.

In the Letters Patent above referred to, the broad idea was set forth ofa time-controlled coin-operating mechanism for regulating the use of avehicle. According to our present invention we have provided suchamechanism wherein upon the insertion of a coin and the operation of apush-rod (1) the coin is deposited in the locked receiving chamber ofthe machine, (2) an indicator is moved forward over a dial to indicatethe length of time of occupation of the vehicle for which prepayment hasbeen made, and (3) the electric. operating-circuit of the vehicle ismade operative.

A represents the casing of the machine and B the time-indicating dial, Crepresents the indicator and D (see Fig. 4:) the push rod by means ofwhich the coin-slide E is moved into the machine after the coin has beendeposited. This coin-slide is of the character shown in Letters PatentNo. 625,123, dated May 16, 1899. When the slide is pushed in, its innerend first strikes against one arm F of a bell-crank-lever (see Fig. 5)the other arm G of which is connected to a slide H carrying aspring-pressed pawl I. This pawl I engages with a ratchet tooth attachedto the indicator C and when the bell-crank-lever is rocked by pressingin the push-rod, the indicator C is given a quarter turn over the dial,thereby indicating the time of occupation of the vehicle for whichpayment has been made.

The inner end of the coin-carrying slide E is provided with a latch J,and when the slide is pushed in to its greatest extent, this latchengages with one arm K of a lever; the push-rod being then released, thespring L forces it back to its normal position and on its passage back,the latch J draws the lever K until its opposite arm M is forced intoengagement with a circuit-closing device N. When in this position, thearm K of the lever (see Fig. 6) has passed a camlock upon an armature O,by which look the lever K is held from returning and breaking thecontact at M N under the tension of the spring P. The hand Q, which, byreason of the advancement of the indicator C a quarter turn, had beenleft a quarter turn behind, proceeds under the operation of a motorwhich may be a spring-actuated motor, such as the clock mechanism asshown to pass through this quarter turn until it contacts with aterminal R mounted upon said indicator C (see Figs. 1 and 7). When thehand Q herein shown as a circuit-closing hand-is in contact with theterminal R a circuit is completed through a battery and bell as shown atthe left ofFig. 7, and the bell is rung warning the passenger that thetime of occupation prepaid is about to expire. If the passenger desiresto extend such time, he may by inserting another coin once more move theindicator forward another quarter turn. the contact being still closedat M N. If he does not desire so to do, the hand Q continues to traveluntil it reaches the second terminal R upon the indicator C. This closesa circuit comprising a battery and a magnet S, Fig. 6) and this magnetdrawing to itself its armature 0, releases the end K of the lever K M,and the spring P withdraws the end M of said lever out of contact at MN, thus breaking the operating circuit in the vehicle. As the clockmechanism will normally continue to operate, the hand Q shortly afterpassing over the contact R will bear against the stop R on the indicatorC and be thereby prevented from further motion, this result beingpermitted by the employment of a familiar friction device T. (See Fig.4:.)

In order to Wind the clock-mechanism conveniently, a Winding arm U isprovided carrying a spring-pawl V which engages with a winding ratchetas shown. In order to keep this pawl clear of the path of the teeth ofsaid ratchet when the latter is moved in a counter-winding direction,apiece 42 mounted on the pawl is arranged to bear against a cam-surfaceW (see Fig.- 3) when the winding arm U is brought back to its normalposition.

WVe claim:

In a device of the 'character described, as manually-operated member, arotatably-v mounted indicator, means operable by said member forrotating said indicator a predetermined amount, a plurality ofcircuitterminals carried by said indicator and amotor-rotatedcircuit-closing hand mounted for rotation about thesame center as saidindicator and turning independently thereof, said circuit-closing; handbeing arranged to contact successively with said circuitclosingterminals in the course of its rotation.

In testimony whereof, we have hereunto subscribed our names this 13thday of December, 1910.
